These functions were only used by the deprecated function
which was deprecated in 3.1, and removed in 3.6.

The capabilities changed ('contextlevel' => CONTEXT_COURSE changed to
'contextlevel' => CONTEXT_MODULE) are:

* moodle/site:accessallgroups
* moodle/site:viewfullnames
* moodle/site:trustcontent
* moodle/site:viewuseridentity

This list came from reviewing the _get_extra_capabilities functions in
all core activities. They were all somewhat inconsistent, but I think it
makes sense that these capabilities are consistently overridable in all
activities. E.g. moodle/site:accessallgroups affects conditional
availability even if there is no other user of groups, and
moodle/site:viewuseridentity and moodle/site:viewfullnames affect the
logs report, if nothing else.

As a result of this, several _get_extra_capabilities functions are no
longer needed, and all the rest have been simplified.

Instead returning the time when the chapter was created or modified we
were returning the time when the book was created or modified.

It was decided to roll only configuration dates and any date related to user content
such as 'timecreated' , 'timemodified' etc should not be rolled forward.

class completion_info will make an extra DB query to retrieve the course if course->enablecompletion is not present

We should be detecting when we are treating files that are linked to
external repositories.
For doing that we'd need to return some additional fields via Web
Services:
- isexternalfile
- mimetype (google docs files use an special one)
- repositorytype (the repository plugin name)

dirname() is a slow function compared with __DIR__ and using
'/../'.  Moodle has a large number of legacy files that are included
each time a page loads and is not able to use an autoloader as it is
functional code.  This allows those required includes to perform as
best as possible in this situation.

Based on a patch by Matthew Cannings, this replaces Book's previous/next arrow
image links with a choice of: no links, image links, or chapter title text links.

Remove old FEATURE_GROUPMEMBERSONLY as no longer required.

This reverts commit 7b7bb92d.

In new logging api, xxx_get_view_actions() and xxx_get_post_actions()
will not be used to identify the paticipation of user. Event's crud
and edulevel status will define user's participation.
